Columbia researchers recently published work using quantum mechanics and a supercomputer to reveal how the world’s strongest, thinnest materials break. The study was inspired by  previous work on graphene and found that several other monolayer materials have a very similar failure mechanism despite having extremely different electronic properties.
Their results contradict previous explanations of why graphene breaks based on a well-known concept in physics called a “Peierls instability”.
Image: Top and side orthographic projections of the distorted structures for (a) graphene, (b) BN, (c) graphane, and (d) MoS2 at equibiaxial strains of 0.212, 0.240, 0.328, and 0.270, respectively. The C, B, N, H, Mo, and S atoms are represented as brown, green, silver, white, purple, and yellow spheres, respectively. Dashed lines indicate the undistorted strained lattice.
